CBS' "Elementary" has cast its Lestrade. British actor Sean Pertwee will assume the role of the Scotland Yard inspector who has alternately appeared as Sherlock Holmes' friend, facilitator or an inept extension of the police force in the characters' various iterations. Pertwee announced his casting via Twitter, noting that he's filming scenes in both London and New York. CBS confirms that Pertwee will appear in the season premiere.

About to shoot Elementary with my chums in London / NY playing Lestrade . Can I get a Whoop Whoop !

Pertwee's casting follows the news that Rhys Ifans will play Mycroft Holmes, the older brother of Jonny Lee Miller's Sherlock. All three actors have previously worked together, starring in the 2000 British film "Love, Honor and Obey." The project also featured Jude Law, who plays Dr. John Watson in the current "Sherlock Holmes" movie franchise alongside Robert Downey Jr. Six Degrees of Sherlock Separation?

Both actors make their debut in the "Elementary" Season 2 premiere on Thursday, Sept. 26 at 10 p.m. ET on CBS. In the episode, Sherlock is called to London to revisit an old case. Despite a falling out, Mycroft allows Sherlock and Joan Watson (Lucy Liu) to stay in his new house.

Academy Award winner Robin Williams returns to series television in THE CRAZY ONES, a single-camera workplace comedy about a larger-than-life advertising genius whose unorthodox methods and unpredictable behavior would get him fired… if he weren’t the boss. Simon Roberts (Williams) is the head of a powerful agency, with the biggest clients and brands in the world, but even more important to him is that his daughter Sydney (Sarah Michelle Gellar) is by his side. As his partner, Sydney is Simon’s exact opposite – focused, organized and eager to make a name for herself, but also too busy parenting her father, which she’d resent if he wasn’t so brilliant at what he does. Joining them in the firm are the dashing and talented Zach (James Wolk); art director Andrew (Hamish Linklater), who’s as hard-working as he is neurotic; and the beautiful and deceptively smart assistant Lauren (Amanda Setton). With his team and his daughter behind him, Simon continues to set the advertising world on fire, and it looks like they are definitely buying what these crazy ones are selling. Emmy and Golden Globe Award winner David E. Kelley (“Ally McBeal” and “The Practice”), Bill D’Elia, Emmy Award winner Jason Winer (“Modern Family”), Dean Lorey, John Montgomery and Mark Teitelbaum are executive producers for Twentieth Century Fox Television. Jason Winer directed the pilot.

MOM is a comedy from executive producer Chuck Lorre starring Anna Faris as a newly sober single mom raising two children in a world full of temptations and pitfalls, and multiple Emmy Award winner Allison Janney as her critical, estranged mother. Christy (Faris) is a waitress at a posh Napa Valley establishment who is four months clean and doing her best to be a good mom and overcome a history of questionable choices. Her sobriety is tested when Bonnie (Janney), her recovering alcoholic mom, reappears chock-full of passive-aggressive insights into Christy’s many mistakes. Bonnie joins Christy’s already complicated circle of relationships: her handsome, married boss – and lover – Gabriel (Nate Corddry); the restaurant’s hot-tempered chef, Rudy (French Stewart); her pretty, 16-going-on-25-year-old daughter, Violet (Sadie Calvano); her sweet but overly honest son, Roscoe (Blake Garrett Rosenthal); her irresponsible ex-husband and Roscoe’s father, Baxter (Matt Jones); and Violet’s clueless boyfriend, Luke (Spencer Daniels). Christy tries to remain positive as she pursues her new path in life, but she faces an uphill battle, surrounded by a dubious support system – and a copious amount of dysfunction. Chuck Lorre and Eddie Gorodetsky (“Two and a Half Men” and “The Big Bang Theory”) are executive producers for Chuck Lorre Productions in association with Warner Bros. Television. Pamela Fryman directed the pilot. Gemma Baker co-wrote the pilot with Lorre and Gorodetsky.

INTELLIGENCE is a dramatic thriller starring Josh Holloway as a high-tech intelligence operative enhanced with a super-computer microchip in his brain. With this implant, Gabriel (Holloway) is the first human ever to be connected directly into the worldwide information grid and have complete access to Internet, WiFi, telephone and satellite data. He can hack into any data center and access key intel in the fight to protect the United States from its enemies. Leading the elite government cyber-security agency created to support him is Director Lillian Strand (Marg Helgenberger), a straightforward and efficient boss who oversees the unit’s missions.

The brains behind the design of the chip is Dr. Shenendoah Cassidy (John Billingsley), whose son, Nelson (PJ Byrne), is jealous of Gabriel’s prominent place in his father’s life. As the first supercomputer with a beating heart, Gabriel is the most valuable piece of technology the country has ever created and is the U.S.’s secret weapon.
